It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-98577 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-98577/ (Markdown: https://insights.sbomify.com/CVE-2026-98577/index.md)","id":"CVE-2026-98577","markdown":"https://insights.sbomify.com/CVE-2026-98577/index.md","name":"CVE-2026-98577","record":{"aliases":["AZL-109131","BELL-CVE-2026-98577","DEBIAN-CVE-2026-98577","GHSA-5pvx-6xr7-wr9x","UBUNTU-CVE-2026-98577"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel NFC","requires_auth":"none","summary":"An attacker can hijack NFC WKS SAPs by exploiting a prefix match flaw in the Linux kernel's LLCP implementation, bypassing service identification.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnfc: llcp: fix WKS SAP hijacking via prefix match in nfc_llcp_wks_sap()\n\nnfc_llcp_wks_sap() compares only service_name_len bytes, so a short\nservice_name like \"u\" matches longer WKS strings like \"urn:nfc:sn:snep\".\nFix by requiring exact length match before strncmp().","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"nfc: llcp: fix WKS SAP hijacking via prefix match in nfc_llcp_wks_sap()","id":"CVE-2026-98577","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"nfc: st21nfca: validate ISO15693 inventory length","id":"CVE-2026-98578"},"packages":[],"prev":{"headline":"nfc: llcp: fix slab-out-of-bounds reads when logging service names","id":"CVE-2026-98576"},"products":["Linux"],"published":"2026-10-18","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"An attacker can hijack NFC WKS SAPs by exploiting a prefix match flaw in the Linux kernel's LLCP implementation, bypassing service identification.","url":"https://insights.sbomify.com/CVE-2026-98577/"}
